Senex Energy Limited announced Wednesday that successful appraisal and development drilling has extended Spitfire oil field in PEL 104 (Senex 60% and operator) in South Australia.
Results from recent drilling have shown that the Birkhead reservoir has a higher top of sand location, lower oil-water contact and greater lateral extent than previously identified. In addition, the quality of the Birkhead Formation sand in Spitfire-4 and Spitfire-6 is better than previously observed. The Spitfire oil field is a combination stratigraphic/structural trap that is defined by sands within the Birkhead Formation and a structural high that is currently interpreted in the vicinity of Spitfire-4.
The results of appraisal and development drilling at Spitfire is summarized below:
The four recent Spitfire appraisal and development wells were drilled on the basis of ‘AVO/Inversion’ enhanced seismic interpretation techniques with the reprocessed Mollichuta 3D seismic survey.
The program has confirmed the use of this technique for exploring and developing the Birkhead reservoir. The inversion data has yielded a significant improvement in targeting the most prolific sands and extending the known range of the accumulation outside previously established areas.
Senex will now reprocess part of the adjacent Aquillus 3D seismic survey using the same techniques. This will improve understanding of the western extent of the Spitfire field to enable further exploration and appraisal wells to be identified in the west and to the north.
Results to Date
Four wells have been cased and suspended as future Birkhead producers at Spitfire oil field since January 2014, with initial production testing providing positive results to date.
